“We spent a long time looking at every development in North County and Paradise View is by far the best. If you want a custom home fully-loaded with fantastic attention to detail (Mike’s attention to detail is legendary), buy one! We did and love our home!”

Graeme & Tamara Ing

We hired Mike Corless & BuildTech to remodel an older home we purchased last year, which was in very bad shape. We brought Mike in during our escrow to advise us what the home would require to make it “more up to date” yet not compromise some of the “retro” flavor we both fell in love with.  To say Mike was patient is an understatement!

We had never been involved in such a huge project before. Mike had a natural ability to understand our needs, and found a way to complete our project at a reasonable budget and on time, even when we got in our own way!

To Whom It May Concern,

Mike Corless and his company BuildTech Unlimited, Inc. is by far one of the most efficient, personable, and professional building company’s in San Diego County. Mike designed a gorgeous home, helped with financing, and with his team of professionals built a dramatic new home along with a total remodel of another home on the same property. All work including rough grading took approximately eight months from start to finish.

Scheduling, quality and functionality far exceeded my expectation and I highly recommend Mike Corless for any kind of construction requiring a true professional.

Dear Mike,

I would like to thank you for designing and building my family an exquisite 2,800 square foot home that feels like a 3,800 square foot home. The dramatic entry with 25′ ceilings, interior loft with balcony, and perfectly designed kitchen make living in this home an absolute joy. Your attention to detail has surpassed my expectations and I consider myself spoiled…homes even in the multi-million dollar price range do not exhibit the level of quality your home provides.

Thanks again for providing me and my family a wonderful place to live.

Kitchen Renovation

Mike Corless has been a godsend to us. We found a bank owned house near our daughter and oldest son. It needed much renovation: new siding, painting inside and out, kitchen modification to allow for more counter space and storage, new kitchen cabinets, damaged 
interior doors replaced and the list goes on.

Compounding our renovation problem was the 500 mile distance between it and our primary residence. Mike made it a non-issue.
He regularly and frequently communicated with us via phone and e-mails (including photos of work in progress). All the work has been of the highest quality. Mike shows up when he says he will and will notify you if he’s going to be late. He truly goes the extra mile.
